Patent EP-0943730-A1 (EP)
Inventor: BAKER SAMUEL M
IPC: D21F7/08
Filed: 1999-03-11
Abstract: A multilayer porous fabric which comprises a porous core fabric (10)
provided with hook means (11), and at least one layer of pre-needled
nonwoven fibrous batt (12A,12B) attached by entanglement onto the hook means (11) by
pressing the core fabric and batt together. The entanglement is
sufficient to anchor the batt reliably to the core fabric, so that the
multilayer fabric is ready for use without further processing. The
porous core fabric may be formed by weaving or as an extruded sheet,
with a plurality of suitably located hook means structures on at least
one of its surfaces. The hook structures engage with and entangle
sufficient fibers from the pre-needled nonwoven batt to provide
adequate attachment preventing the batt from separating from the core
fabric enabling the multilayer fabric to be handled before use, for
example for installation in a papermaking machine press section. The
batt is pre-needled to a desired density before attachment to the core
fabric. In many circumstances, compressive loads applied to the
porous fabric serve to enhance and improve the level of entanglement
of the batt onto the hook means.
